Abstract: A controlled infusion container suitable for infusing substances into a liquid into which it is immersed includes a container for the infusible material fabricated from porous sheet material folded upon itself providing a reservoir for the infusible material. The distal edges are folded upon themselves to form a relatively small overlap portion which is then sealed to provide a centrally disposed opening. A handle is inserted into the opening extending therein and is fastened to the remaining open edge of the container retaining the infusible substance therein. By inserting the assembly into a liquid and gently providing for up and down and lateral motion a pumping action created by the handle provides efficient infusion of the infusible substances into the liquid.
